Code Library |
||
|
|
||
|
The computers
primarily available for use are the group's own Sun
UNIX workstations. There is also the VAX system operated by the Computing and
Information Systems (CIS) department, but this system tends to have older
versions of the codes, and new users will find more help available if they
are using the workstations. |
||
|
In order to
run the codes on local systems, look for executables in the directories: |
||
|
|
UNIX
workstations: /usr/local/atomic/bin |
|
|
|
VAX
system: USR2:[10104.ATOMIC1.EXE] |
|
|
We encourage
use of the SLATEC numerical library, which contains a wide variety of
numerical algorithms written in FORTRAN. Source code is available in the
directories: |
||
|
|
UNIX
workstations: /usr/local/atomic/slatec |
|
|
|
VAX
system: USR3:[PHY.SLATEC] |
|
|
More
information is available on the group's web site at: |
||
|
|
||
|
The group
has books available on various operating systems, languages and software,
also hardcopy documentation on the codes. |
